If you want the fastest chip, the best battery, or the camera that fits your life, this one post will save you hours of reading.
I pulled official specs from Samsung and Apple, plus testing and reviews from top outlets. I compared real numbers for screen, battery, cameras, performance, and price. I flagged what matters to daily use, not just marketing lines. Sources include Apple’s and Samsung’s spec pages and major tech reviews.
Quick verdict
The S25 Ultra is the pick if you want flexible cameras and S Pen support. The iPhone 17 Pro Max is the pick if you want long software support, top raw performance, and iOS ecosystem polish.

Display and media experience
Samsung keeps pushing bright AMOLED panels that show pop and deep blacks. The S25 Ultra uses an LTPO 2X panel with 120 Hz smoothing and extreme peak brightness in HDR. Apple’s iPhone 17 Pro Max uses a high-brightness OLED with ProMotion and tight color tuning for movies and HDR. If you watch HDR movies and want the brightest highlights, both do great; Samsung sometimes wins on raw brightness, Apple on color accuracy and consistent brightness in sunlight.
Performance and thermals
The iPhone 17 Pro Max runs Apple’s A19 Pro chip with strong single-thread and multi-core performance. Samsung’s S25 Ultra uses the latest Snapdragon (or Exynos in some regions) tuned with Galaxy’s thermal design and sometimes a vapor chamber. In daily apps and games the differences are small; iPhone often wins raw benchmarks, while Samsung wins in flexibility (more RAM, background apps).
Camera comparison — table and notes
| Use case | Samsung S25 Ultra | iPhone 17 Pro Max |
|---|---|---|
| Main image quality | 200 MP sensor, huge detail, strong HDR processing, great low light with pixel binning. | 48 MP system with Apple color science, excellent dynamic range, very reliable skin tones. |
| Telephoto & zoom | Periscope 5x opt plus software reach beyond 100x; strong for long-distance shots. | New tele strategy with 4x and sensor crop up to 8x delivering very clean zoom and consistent color. |
| Ultrawide | 50 MP ultrawide with wide field and good low-light. | 48 MP ultrawide with consistent processing and better video stabilization. |
| Video | Excellent 8K-capable options, Pro modes on Samsung; stabilization is solid. | Apple focuses on cinematic tools, multistream capture, and pro video workflows; great color and codecs for editing. |
If you love long-range shots, Samsung’s periscope wins. If you want consistent, edit-ready footage and color, Apple is easier to work with.
Battery life and charging
Samsung S25 Ultra lists a 5,000 mAh battery and supports 45W wired charging and Qi2 wireless. Apple lists video playback times (up to 39 hours for iPhone 17 Pro Max) and Apple’s specs mention fast-charge numbers with the right adapter. Independent testers show the S25 Ultra gives heavy-screen users a full day easily, and iPhone 17 Pro Max often stretches longer thanks to silicon efficiency and software optimization.
Software, updates, and ecosystem
Samsung gives a lot of customization, an S Pen experience, and Galaxy AI features. Apple offers iOS 26, deep integration with Mac and iPad, consistent app quality, and longer update windows (usually 6+ years). Choose Android if you want flexibility and features. Choose iPhone if you value long-term updates, resale value, and ecosystem sync.
